REMOVAL & INSTALLATION
To remove the wiper blade, turn the blade at an angle to the arm, then move the blade down so its spring clip moves off the hook in the arm and remove the blade. Reverse to install.
To remove the arm, on models before 1973, remove the cap nut where the arm attaches to the windshield wiper drive shaft and lift off the arm. On 1973 and later models, the retaining nut is covered by a plastic cap. Remove the cap, remove the nut and remove the arm. When installing wiper arms, make sure they park at the bottom of the swept area and that they cover the entire swept area when in operation.
